    摘要: Neplanocin A derivatives of the formula ##STR1## wherein R.sub.1 and R.sub.2 are hydrogen or benzoyl, R.sub.3 is hydrogen or OR.sub.8, R.sub.5 is hydrogen or acetyl, R.sub.6 is hydrogen, acetyl or benzoyl, when R.sub.3 is hydrogen, R.sub.4 is hydrogen or halogen, hydroxy, acetoxy, acetylthio, amino or azide, and when R.sub.3 is OR.sub.8, R.sub.4 is hydrogen, R.sub.8 is hydrogen or acetyl, or R.sub.8 and R.sub.5 together form benzylidene, and at least one of R.sub.8, R.sub.5 and R.sub.6 is other than hydrogen. The compounds of the present invention have inhibitory action for the growth of L 5178 Y cells and have the same or superior activity as neplanocin A, and hence are useful as antitumor agents.
